Chemical Reactions Vocab Bingo - Call List

(Print) Use this randomly generated list as your call list when playing the game. There is no need to say the BINGO column name. Place some kind of mark (like an X, a checkmark, a dot, tally mark, etc) on each cell as you announce it, to keep track. You can also cut out each item, place them in a bag and pull words from the bag.

  1. products
    final substance at the end of a chemical reaction
  2. etch
    chemical process that cuts into a solid surface
  3. endothermic
    process that absorbs energy; temperature decreases (product is cooler than the reactants)
  4. open system
    A system that allows matter or energy to enter or escape.
  5. constraint
    something that limits the solution to a problem
  6. exothermic
    process that releases energy; temperature increases (product is warmer than the reactants)
  7. physical change
    change that occurs when the particles of one substance mix with another substance, particles do not change
  8. dissolve
    mix into another substance at the scale of individual particles
  9. trade-off
    desirable outcome given up to gain another desirable outcome
  10. chemical change
    substances interact to form a new substance
  11. reactants
    original substances before a chemical reaction takes place
  12. criteria
    a minimum requirement for how the design must function
  13. atom
    The basic building block of matter Contain protons, electrons and neutrons
  14. circuit board
    a thin board with copper lines on the surface
  15. evidence
    information that supports or refutes a claim
  16. chemical reaction
    process where chemical change occurs
  17. compound
    Two or more different types of atoms held together by a chemical bond EX: : H2O or CO2
  18. state
    physical form of matter: solid, liquid, gas
  19. chemical equation
    a symbolic representation of the reactants and products in a chemical reaction
  20. thermal energy
    total energy of motion of the particles in a sample of a substance
  21. precipitate
    insoluble solid formed when two liquids mix
  22. law of conservation of mass
    The principle (or scientific law) that mass is neither created nor destroyed during a chemical reaction. See law of conservation of mass.
  23. molecule
    Two or more atoms held together by a chemical bond (any two or more atoms) EX: H2O or O2
  24. conserved
    saved, neither gained nor lost
  25. mass
    amount of matter in an object
  26. reclaim
    to retrieve waste material so it can be used again
  27. prototype
    an early sample of a product that provides information about how the device or system works
  28. closed system
    A system that does not allow matter or energy to enter or escape.
